SPECIFICATION forming part Of Letters Patent N0. 693,719, dated February 18, 1902. Application filed October 11, 1901. Serial No. 78,857 (No model.)

To aZZ whom, it may concern.- lock to which my invention is applied. Fig. Be it known that I, OSCAR KATZENBERGER, 7 is a sectional View illustrating the applicaa citizen of the United States, residing at San tion of my in vention to a street-letter-box lock.

Fig. 5 is a detail dogs H H in Figs. 2 and 3 are pivoted at I I section. Fig. 6 is a sectional View of a padand are held in position by the springs J J,

fastened at K K. These dogs and their corresponding teeth on the ratchet-wheels are so shaped that when the wheel is on the axle in the position as shown in Fig. 2 the knob B can be turned only to the right, while if it is reversed and placed on the axle as shown in Fig. 3 the said knob may be turned in either directionthat is, either to the right or to the left.

Figs. 1., 2, 3, and 4 show the application of the principles of this look to a lock for postoffice boxes and other similar locks. L represents the bolt, pivoted at M. The tumblers O C 0 work directly against the main bolt. When the bolt is in position as shown in Fig. 4, the door is locked, the end of the bolt being behind the projection N on the frame of the door Q. When the tumblers C O O are all turned flat side up, the bolt L will fall down to the opening 0, (see Fig. 3,) and thus allow the door to open. The door may be opened from the inside without lining up the tumblers by lifting the end of the bolt L up to the opening provided for the purpose, and the door may be closed in like manner by lifting the bolt through the opening before referred to. This last operation is facilitated by giving a slight slope to the projection N from the outside. The projection N is also sloped slightly from the inside to minimize the chances of changing the combination accidentally while closing the door.

Fig. 5 represents the principles applied to a padlock. The tumblers O G O O operate against the bolt R, which is pivoted in the center, as shown. The spring T throws the neck 5 open as soon as the tumblers C O C G are lined up, and the spring U throws the bolt back, disengaging the bolt from the neck, substantially as shown.

Fig. 7 shows the application of the principles to a street-letter-box lock and other locks of similar construction. The tumblers O O C operate directly against the bolt V, substantially as shown.

Figs. 1, 2, and 4 show the operation of the springW, fastened to the back of the door Q in such manner as to operate against the jamb of'the door and throw it open as soon as unlocked and to keep it open until the combination is thrown.

The operation of the lock is substantially the same as described in my former patent, No. 678,956, the notches in the ratchet-wheels taking the place of the depressions and the dog the place of the pointed spring.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a lock of the character described, the combination, with a pivoted bolt, of a circular tumbler having a portion of one face cut away or flattened, the edge being left circular, a concavo-convex spring applied to such tumbler, a tumbler-spindle having a knob, and means for locking the tumbler, substantially as shown and described.

2. In a lock of the character described, a tumbler, which is circular in form, having a portion of one face cut away, the edge being left intact, as shown and described.

3. In a lock of the character described, a ratchet-wheel having a smooth place for the beginning of the combination, a dog to operate against such ratchet-wheel and a spring to hold such dog in position; the teeth on such ratchet-wheel and the dog being so shaped as to ,enable the said wheel to be turned either to the right or to the left; and means of fastening such ratchet-wheel onto the axle carrying the tumbler; the purpose of such ratchet-wheel, dog, &c., being to communicate the combination either by hearing or by touch, substantially as set forth.

4:. In a lock of the character described, the combination, with the casing, and pivoted bolt, of a tumbler, which is circular and has a portion of one face cut away, a concavoconvex spring bearing upon the tumbler, a spindle whereon the tumbler and spring are mounted rotatably, a ratchet-wheel fixed on the spindle and having a portion of its periphery smooth, and a pivoted dog which engages such Wheel, all arranged and operating as shown and described.

5. In a lock of the character described, the combination, with casing, pivot-ed bolt-spindle, a circular tumbler cut away on one face, a spring acting on the tumbler and a ratchetwheel fixed on the spindle and having one side flattened, of a pivoted spring-pushed dog having a V-shaped head adapted to engage the ratchet and thus permit the latter to be rotated in either direction, whereby the combination is communicated either by touch or hearing, as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

OSCAR KATZENBERGER.
